Abstract: FIELD: medicine. 
     SUBSTANCE: invention refers to medicine, namely to radiation diagnostics and oncology, and can be used for differential diagnostics of pancreatic cancer. Magnetic resonance imaging, 1H single-vole spectroscopy and post-treatment are performed. After marking and calibrating, T2-weighted series in three planes crossing the pancreas and axial T1FS, LAVA and DWI are performed: b = 0 b = 1000 and T1 is a double gradient echo in phase and antiphase. In the RadiAnt software system, a region of the most pronounced changes is selected, enveloped with an oval or round border. Structural heterogeneity coefficient (HG) is calculated by formula: HG = SD/SI, where SD is standard deviation, SI is average signal intensity. Portion of lipids in the pancreas is determined on the basis of the Dickson method, wherein a dual gradient echo in-phase/out-of-phase is used. Proton single-cumulative spectroscopy of the same region of suspicious changes with respect to cancer is carried out. Data is transmitted to a computer with a program for processing spectra, and spectrum peaks in the Tarquin program are determined. Value of the Lactate signal in the au is measured, and the value of the calculated diffusion coefficient (ADC) by DWI is measured. When determining a solid tissue having a KG value in T2 of 0.13-0.19 and a KG value in T1FS of 0.1–0.165, with an ADC value of 0.001–0.0016 mm 2 /s, a fraction of lipids of 1–3 %, Lactate 1–3 au is diagnosed with a malignant tumour. If Lactate 0–1 au, lipid fraction to 14–18 % and ADC value 0.0014–0.0022 mm 2 /s, chronic pancreatitis is diagnosed. 
     EFFECT: method provides higher accuracy of differential diagnosis of infiltrative pancreatic formations due to declared quantitative traits determined by MRI.

Abstract: FIELD: oil and gas industry. 
     SUBSTANCE: invention relates to oil and gas industry, in particular to seismic methods for determination of formation areas with different permeability. Disclosed method of determining fracture porosity of rocks involves forming a set of samples of analyzed rock, experimental determination of total fractional porosity of each of said samples in atmospheric conditions, also experimental determination of seismic waves propagation speed and common fracture porosity in samples of analyzed rock in conditions simulating formation conditions, measurement of seismic wave propagation speed in the analyzed rock and calculation using the obtained data. Initiation of seismic waves is carried out from a seismic well in which reflected waves are recorded to determine boundaries of zones with different fracture porosity, waves attenuation to determine speed and direction of their propagation are determined by seismic sensors located in azimuth relative to seismic well in recording wells. Calculated stratigraphic boundaries of the zones are determined using a common depth point method — CDPM 2D and/or 3D, with density of seismic profiles of at least 2 line km/km 2 . To specify profile of zones with crack porosity, at least by 20 % larger than total fracture porosity in these zones through additional seismic well with registration of reflected waves, and in additional recording wells wave attenuation parameters are measured with subsequent calculation and correction of boundaries and location of selected zone. 
     EFFECT: high accuracy of obtained results owing to use of overlapping values of reflected waves and damped waves, as well as duplication of measurements for areas of the formation with high porosity of rocks.

Abstract: FIELD: medicine. 
     SUBSTANCE: invention relates to medicine, namely to anesthesiology and intensive care, and can be used for securing an epidural catheter by forming an intracutaneous loop and a cutaneous loop of the epidural catheter. A large subcutaneous canal is formed from the site of epidural access to the first exit of the epidural catheter to the skin. An epidural catheter is passed in the small subcutaneous canal by means of a modified spinal needle with an outer diameter of 0.52 mm or 0.45 mm, wherein said canal begins at a point located 5 mm lateral to the point of the first exit of the epidural catheter to the skin from the large subcutaneous canal. When forming the small subcutaneous canal, the modified spinal needle with the epidural catheter secured thereon is passed under the skin to a distance of 10 mm in the caudal direction, followed by passing the epidural catheter secured on the modified spinal needle into the lumen between the skin surface and the cutaneous section of the epidural catheter located on the skin surface between the point of the first exit of the epidural catheter to the skin and the point of entry of the epidural catheter into the small subcutaneous canal, thus forming an intracutaneous loop of the epidural catheter. The modified spinal needle with the epidural catheter secured thereon is then inserted into the lumen formed between the skin surface and the epidural catheter located between the point of the second exit of the epidural catheter to the skin and the point of entry of the epidural catheter into the small subcutaneous canal, thus forming a cutaneous loop of the epidural catheter. The two loops of the epidural catheter - the intracutaneous loop and the cutaneous loop - are therein formed after the epidural catheter is passed in the subcutaneous canal at the point of exit of the epidural catheter from the subcutaneous canal. 
     EFFECT: method ensures reliable securing of the epidural catheter, preventing external dislocation thereof, due to formation of loops.

Abstract: A system for selecting a signal having a median frequency from a plurality of periodic signals of different frequencies. In one embodiment, three such periodic signals are converted into corresponding pulse sequences, each having a duty cycle of approximately unity and a frequency which corresponds to the frequency of its associated periodic signal. An output signal is generated which assumes a first logic state when a positive signal slope of a first pulse sequence, which places the first pulse sequence in a first logic state and occurs while the output signal is in a second logic state, is followed by a further positive signal slope of a second pulse sequence, while the first pulse sequence is in its first logic state. The output signal assumes a second logic state when successively negative pulse sequence slopes occur.

Abstract: The disclosure relates to a rotary pump especially for corrosive liquids including an impeller rotating in a working chamber. A spirally wound duct leads from one surface of the working chamber to the outlet pipe of the pump. The upstream end of the duct obliquely enters the working chamber, whereby the end portion of the duct is laterally open towards the chamber and forms a channel in the wall of the chamber. The duct winds helically around the rotation axis of the impeller, having an inside wall at a progressively decreasing radial distance from said rotation axis and a progressively increasing pitch when viewed in the direction of the flow. A feature is the provision of the wound duct in the form of a helix as an open groove formed on the outer surface of a solid stator body and closed by an encompassing casing. A further feature is the provision of a relatively loose, elongated drive shaft from a motor to the pump impeller disposed within a guide tube and a circumferential clearance between the shaft and the tube for leakage flow of liquid being pumped to lubricate the shaft wherein a bypass port is provided in the guide tube for return of the leakage flow upstream of a restriction in the clearance. The restriction increases pressure in the clearance to dampen lateral oscillation of the shaft in the tube. No seals are used for the shaft thereby precluding the tendency of seals to stick during prolonged rest periods.
